Question

If electri flux is 0 then is it necessary that no charge is present inside gaussian surface.

Answer 1

hey,..here is your answer friend..

I learned that the vector flux through any closed surface is always 0. So if you have a sphere(closed surface) and you put it in an uniform electric field, then the total flux is 0.

However, the Gauss's law states that the electric field flux through a closed surface equals the enclosed charge divided by the permitivity of free space. Shouldn't it be 0? What am I misunderstanding here?

Any explanation will be appreciated.

Answer 2

No, it is not necessary that there would be no charge in the gaussian surface! Because electric flux of the surface is 1/Enot times the net charge enclosed inside the surface! So it may possible that there are a number of charges available inside the surface but the net charge becomes zero!!
